14 Emma spent: Emma's total = 1 : 4
Amount that Cindy spent
= 4 x 1 u
= 4 u
Amount that the three girls spent
= 1 u + 4 u + 261
= 5 u + 261
Amount that the three girls spent
= 1335 - 764
= $571
5 u + 261 = 571
5 u = 571 - 261
5 u = 310
1 u = 310 ÷ 5 = 62
Amount that Anna and Cindy had in the end
= 764 - 3 u
= 764 - 3 x 62
= 764 - 186
= $578
Answer(s): $578
